For most of human history, the materials behind great artifacts were a matter of educated guesswork. Was that dagger really made from a fallen star? How did a Roman glass cup change color from green to red? What alloys did ancient mints and silversmiths actually use? X-ray fluorescence (XRF) has quietly become one of the main tools for answering these questions. It lets scientists determine what ...
In the production of galvanized rolled steel products, it is critically important to strictly control the composition of metallic coatings. Modern protective coatings on steel – from traditional zinc to complex zinc-aluminum-magnesium alloys – contain alloying elements (additions) such as aluminum (Al), magnesium (Mg) and silicon (Si). These additions have a strong influence on the ...
Ilmenite and Its Significance: Where It’s Used and Why Composition Matters Ilmenite is a mineral—the primary source of titanium—occurring as iron–titanium oxide (FeTiO3). It is a raw material for producing titanium dioxide (TiO2), a widely used white pigment, and for metallic titanium. About 95% of all mined titanium feedstock is processed into TiO2 pigment used in paints ...
Introduction To obtain reliable and reproducible results by X-ray fluorescence (XRF) analysis, it is crucial that the sample be as compositionally uniform as possible and optimally prepared in terms of structure and surface. This is especially important when working with powdered materials—ranging from ore and coal to pharmaceutical and ceramic mixtures. In this article, we will show how ...
Introduction Soil is the foundation of agriculture and ecosystems, yet industrial activities and pesticides often introduce toxic metals like lead, cadmium, or mercury. Rapid assessment of soil composition is essential for farmers, environmental engineers, ecologists, and regulators. X-ray fluorescence (XRF) delivers multi-element results in minutes without complex lab work, making it an ...
Crucibles and casting dishes are needed to produce fused beads with the VITRIOX ELECTRIC and VITRIOX GAS fusion machines. A special platinum and gold alloy with a composition of 95% Pt and 5% Au is commonly used. This alloy is characterized by mechanical durability and, due to the gold content, low material adhesion. In addition, this alloy is also available as FKS platinum, i.e., by adding a ...
X-ray fluorescence (XRF) analysis is widely recognized for its accuracy and versatility across numerous industries. Yet, several myths persist about this technology, often causing businesses to overlook its powerful capabilities. In this article, we’ll dispel five common misconceptions about XRF analysis and clarify why it’s an accessible, efficient, and highly practical method for ...
In the present scenario, the pellet method was employed. The EDX8800 MAX floor-standing XRF spectrometer was utilized to expeditiously analyze the composition and grade of magnetite, attaining satisfactory levels of measurement accuracy and precision. ...
The nomenclature "monazite" stems from its propensity to exist preponderantly in the form of single crystals. It is a phosphate mineral that encompasses cerium and lanthanum and constitutes one of the principal minerals within rare earth metal ores. This mineral frequently incorporates elements such as thorium and zirconium. Monazite crystallizes in the monoclinic system, with its crystals ...
The following list encompasses instruments that are commonly used for environmental analysis: Avance III 400MHz NMR: applied for Component Analysis, Micro-analysis, Surface Analysis, Structure Identification, Performance Analysis, Toy Analysis, Polymer Material Analysis, Spice Analysis, Food Analysis, Environmental Analysis, Mineral Element Analysis, Analysis of Metal Materials Avance III 600MHz ...
To compensate for this effect, it's necessary to increase the power of the X-ray tube, specifically by increasing the tube current at low anode voltage. In the Elvatech range of XRF spectrometers, this is implemented in the flagship model, ElvaX Pro, which is equipped with an X-ray tube with a 1000 µA current instead of the standard 200 µA tube. This ...
Research has shown that tiny pieces of plastic are almost everywhere—in the air, water, food, and even in the human body—but it's unclear what risks nano- and microplastics pose to the environment or human health. Researchers are using lessons from nanotoxicology to begin investigating the risks of microplastics, according to a cover story in Chemical & Engineering News, the ...

Abstract A quantitative analysis of Iron in flour via Xenemetrix EDXRF Laboratory Spectrometer System was performed by model EX-3600M. The minimum detection limit for Fe in flour matrix was determined to 0.8 ppm at 3 sigma. Objective To design an easy method by using EDXRF technique for quick and convenient measurements of Fe in flour at the level of tens of ppm. Background EDXRF is a ...
Abstract The minimum detection limits of several different elements in water and in oil solutions were determined on X-Calibur with a SDD detector installed or a Si-PIN diode detector installed. The MDL was determined at 3 sigma and 300 seconds acquisition times. The result is reported here. Objective To perform a quantitative comparison between the performance of X-Calibur with a SDD ...

Abstract. An Xact 625 ambient metals monitor was tested during a three-week field campaign at the rural, traffic-influenced site Härkingen in Switzerland during summer of 2015. The objective was to characterize the handling and operation of the instrument, evaluate the data quality by intercomparison with other independent measurements, and test its applicability for aerosol source ...
Thermal decomposition method was employed to prepare a Ti/SnO2-RuO2 electrode, on which electrocatalytic degradation of bromocresol green (BCG) was investigated in detail. Scanning electron microscopy, an X-ray diffraction analyzer and an X-ray fluorescence spectrometer were adopted to characterize the morphology, crystal structure and element analysis of the as-prepared Ti/SnO2-RuO2 ...
Fluorine compounds possess a wide range of properties, including flame retardance, water repellency, anti-fouling property, and heat resistance, and are therefore used in a wide range of fields from articles for everyday use to semiconductors. However, since the 1980s, the problems of global warming and ozone depletion in addition to the potential for bioaccumulation have led to strengthened ...
